Wayne,

Don't worry the mass of the wing will do a fine job of crushing your spine into the instrument panel anyway. It is around half the empty mass anyway.

Always hit the ground moving parallel to it at the lowest possible forward speed.

Yes I guess you could move the battery pack fore and aft to adjust the C of G in flight. George Moffatt once had a system of pumping mercury in a Nimbus 3.

If Dg put their battery pack in the motor compartment, per the latest
newsletter, or anywhere in the fuselage as they reckon is safer (I can see
their point but would call it bunk, If I had a heavy landing I would want
that battery mass to be within the cart-wheeling wing some 50 metres in
front of me, not crushing my spine into the instrument panel)- perhaps they
could put it on a sliding beam?

Just a few hundred millimeters would allow the mass to move the overall CG
for improvements to run/climb attitude, surely?
Or is that a false theory?

Input please!-enlighten me (hey there is a pun)
